Name: Zirconium metal, Zirconium wire

Molecular formula: Zr

CAS: 7440-67-7

Molecular weight: 91.22

Description

Zirconium is a silver gray metal. The surface of zirconium is easy to form a layer of oxide film with luster, so its appearance is similar to that of steel. It is corrosion resistant, but soluble in hydrofluoric acid and aqua regia. At high temperature, it can react with non-metallic elements and many metal elements to form solid solution. Zirconium has good plasticity and is easy to be processed into plates, wires, etc. The content of zirconium in the crust is 19th, almost equal to that of chromium. Zircon minerals of industrial value in nature are mainly zircon and zircon. The better method in industry is molten salt electrolysis with ZrCl4 or k2ZrF6 as raw material.

Used

Zirconium, with small thermal neutron capture cross section and outstanding nuclear performance, is an indispensable material for the development of atomic energy industry and can be used as reactor core structural material. Zirconium powder is easy to burn in air and can be used as detonator and smokeless powder. Zirconium can be used as an additive for deoxidizing and desulfurizing high-quality steel, and also as a component of armor steel, artillery steel, stainless steel and heat-resistant steel. Zirconium alloy has good corrosion resistance, moderate mechanical properties and low atomic thermal neutron absorption cross section in high temperature and high pressure water and steam at 300-400℃, and has good compatibility with nuclear fuel. It is mostly used as core structural material of water-cooled nuclear reactor.
